Title: Improvements relating to the treatment of textile and like materials
Inventor: HANNAY ROBERT STEWART ERSKINE
IPC: D06B19/00
Filed: 1948-05-04
Abstract: Textile or like materials are heated, prior to passing them through a molten metal bath, to a temperature above the freezing-point of the metal bath.  Preferably the heated textile materials are passed through a layer of treating liquor floating on the surface of the molten metal, or they may be impregnated with a treating liquor and then passed through a treating liquor floating on the molten metal. When the treating liquor contains a hydrosulphite, an anti-oxidant such as glucose, benzaldehyde or tannic acid is added to inhibit the formation of sludge on the molten metal.  The cloth may be heated by passing over steamheated cylinders, by passing through a casing through which hot air is blown or by passing between electrically-heated radiant surfaces.  The cloth on leaving the metal bath may similarly pass through a column of treating liquid floating on the surface of the metal as described, for example, in Specification 661,086. Specifications 620,584 and 663,066 also are referred to.

The back C of the chair is pivoted to the seat c and is supported normally in a near vertical position by a U-shaped stay c' pivotally connected to a U-shaped support C' capable of sliding relatively to the frame A. When the frame is required to support a cot, the back C and the footrest D are pivoted to form a horizontal continuation of the seat and are supported in this position by the frame C' which is extended rearwardly and by a supporting stay D' which engages brackets d' on the front axle a'. When the footrest is in the normal position the stay D' abuts a bar d<SP>2</SP> riveted to the frame. The handle D' may be released from the arms D<SP>2</SP> to permit them to be pivoted to lie flat on the frame, and a brake A<SP>2</SP> is provided. The Provisional Specification describes also, a push chair whose back is supported in the horizontal position by a transverse U-shaped stay, the ends of the limbs being pivotally connected to downwardly bent rear ends of the frame sides. The transverse stay also supports the back when the latter is substantially vertical. A flap or rods near the upper edge of the back may be turned into a vertical position when the back is horizontal to prevent rearward movement of the cot.

Abstract: 234,981. Hough, T. May 20, 1924. No Patent granted (Sealing fee not paid). Condensers.-In electric condensers of fixed capacity, the elements are embedded in insulating material which is moulded around them under pressure when in a plastic condition, and provision is made for preventing shearing of the plates by the moulding pressure. The plates a are assembled, together with interposed sheets of insulating material such as mica, upon terminal screws c and are then placed upon a layer of thermoplastic material e in a mould which is then filled with thermoplastic material and closed. The whole is then consolidated under heat and pressure and, after cooling, the condenser is removed from the mould as a solid hard block from which the terminal screws c project. "Bakelite," ebonite, synthetic resin, and hard rubber are mentioned as materials which may be employed. The means for preventing the projecting ends b of the plates from being sheared cff under the moulding pressure comprise strengthening plates d of metal, or a sheet of fibre placed over the plates a before placing them in the mould.

[Also in Group XXVIII] In the apparatus described in the parent Specification wherein a number of bristle-like fingers 99 extend from aligned core members 95, 96 attached to a housing 87 enclosing power means for oscillating the housing to impart to at least a part of each core member an oscillatory motion transverse to the axes thereof to cause the apparatus to travel through a conduit 88, each of the fingers has, at or near the base thereof, a coil 100 through which the outer extremity of the finger is attached to the core member. As shown, the housing encloses an electric motor the driving shaft 92 of which carries eccentric bob weights 93, 94 located 180 degrees out of phase with one another so that when the shaft rotates the housing wobbles in such a manner that opposite ends thereof tend to describe circles about the axis of the conduit. The fingers 99, Fig. 6. are each formed integrally with the helical coil 100 the axis 100a of which is parallel with the portion 99a of the finger when the latter is not subjected to constraint by the walls of the conduit, and an anchor portion 99b provided with a bent-over tip 99d and clamped between coaxial, disc-like aluminium spacers 101, each pair of spacers securing twelve fingers ; a stack of spacers, forming the core members, are secured between flanges 102, 103. The faces of the spacers are inclined at an angle of 15 degrees to a plane normal to the axis 101a of the core so that the fingers are inclined to that plane correspondingly.

Title: Improvements in starting devices for internal combustion engines
IPC: H02P9/00
Filed: 1920-05-04
Abstract: 142,837. Bosch Akt.-Ges., R. Feb. 13, 1915, [Convention date]. Turning-gear.-In an electric starter in which the armature a of the starting-motor is displaced axially to bring a pinion d into mesh with an engine member e, a main switch h leads current to the field coils b, the armature being in a branch circuit, and a second switch n sending full current to the armature is closed automatically by the displacement of the armature. In the form shown in Fig. 1, the main switch, h is closed by means of a push k and coil i, and current is supplied to the field coils through a conductor l, a resistance w, one side of a switch n, and a conductor z<1>. A second conductor z<2> supplies both the armature and the field coils. The resulting displacement of the armature closes a spring contact s and earths a coil q, which draws down the switch n, cutting out the resistance w and the conductor z<1> and supplying full current through the conductor z<2> to the armature and the field coils. A coil v is not strong enough to move the switch n, but holds it on the contacts m<1>, m<2> when moved by the coil q. When the engine starts, the push k is released and the switch h opens. In a modification, an auxiliary coil, which holds the switch h closed if the push k is released, has its circuit closed and opened by the movement of the armature; a hand-actuated switch may be provided for breaking the circuit of the holding- coil in case the engine fails to start. In the form shown in Fig. 4, the circuit of the holding- coil i<2> is closed by contacts 10, 13 and is broken automatically after a time by an air cataract comprising a piston 15 connected to the armature shaft of the motor and a piston 16 carrying the contact 10. When the armature moves axially, the contacts 10, 13 are closed by the piston 15 acting through the air cushion 17 and piston 16. The vacuum created behind the piston 15 is then in communication with the air space 17 through a fine tube 21. After a time, the air from the space 17 has escaped sufficiently to allow a weak spring 18 to return the piston 16 and open the contacts 10, 13. Specification 29932/12 is referred to.

Abstract: 259,141. Henrion, G. P. M. May 13, 1926. Addition to 245,433. Lighting systems. -In a modification of the headlightcontrolling apparatus described in the parent Specification, the fixed headlight is dimmed when the movable headlight is given a comparatively small angular movement, e.g. 10‹, and while its movement is restricted to a definite angular zone, e.g. 15‹, and means are provided so that the movable headlight may be given any angular movement, if desired, without dimming the stationary headlight. The circuits of the main lamp filaments 9, 12 and the auxiliary lamp filaments 10, 13 of the movable and stationary headlights may be arranged as shown in Fig. 4. The casing 8 of the movable headlight is electrically connected to the vehicle frame, while the casing 11 of the stationary headlight is electrically connected to the casing 8 or directly to the vehicle frame when contacts 24, 25 are closed so that both main lamp filaments are lit when the switch lever 15 engages a contact 17. When the contacts 24, 25 are broken owing to the movement of the movable headlight to the non-dazzle position. the circuit through the main lamp filament 12 of the stationary lamp is closed only through the filaments 12, 9 of the auxiliary lamps so that the main lamp filament 12 burns dim owing to the comparatively weak current passing through it. The movement of a switch lever 15 from the contact 17 to a contact 18 lights the auxiliary lamps and extinguishes the main lamps in the normal position of the headlights.
